Screw Sdm Csk Ribbed Zinc 8-18 X 20

PRODUCT DESCRIPTION

Coarse thread self drilling screw designed with a ribbed countersunk head allowing for easy self embeddment and a flush finish. Coarse thread allows for a faster install, whilst the self drilling tip eliminates the need for pre-drilling. Often used for fixing cement sheeting or villa board to steel framing. These screws have a hardened steel self drilling point (tek point) which cuts through mild steel without the need for pre-drilling (see product attributes for material thickness constraints). Also ideal for fixing panelling to steel frame sections.
